| 摘 要： | 研究了不同浓度(10-2、10-4、10-6、10-8、10-10 mg/L)的萘乙酸(NAA)对一串红种子发芽率、幼苗苗长、主根长、侧根数、测量根系活力及叶绿素含量的影响,以期优化萌发条件,提高种子萌发率,促进幼苗生长,为一串红的科学种植提供依据。结果表明:10-10～10-8 mg/L的NAA可以增加一串红种子的发芽率、主根长、侧根数、叶绿素含量和根系活力。

| Abstract: | The effects of naphthylacetate(10-2,10-4,10-6,10-8,10-10 mg/L)on seed germination rate,seedling shoot length,seedling main root length,lateral root number,root activity and chlorophyll contents of Salvia spleredens were studied.In order to optimize the germination conditions,promoting the germination rate and seedling growth provided basis for planting Salvia spleredens.The results showed that naphthylacetate of 10-10~10-8 mg/L increased seed germination rate,seedling main root length,lateral root number,chlorophyll contents and root activity. |
